Description

A unique combination of PCR products and a number of proprietary plasmids digested with appropriate restriction enzymes to yield 12 fragments, suitable for use as molecular weight standards for agarose gel electrophoresis. The DNA includes fragments ranging from 100-3,000 base pairs. The 500 and 1,500 base pair bands have increased intensity to serve as reference points. The approximate mass of DNA in each band is provided (0.5 μg a load) for approximating the mass of DNA in comparably intense samples of similar size.The ladder is ready-to-use, and is premixed with loading buffer dye for direct loading on gel.

Phenylmethylsulfonyl fluoride (PMSF)

P-470-50 50 g $ 187.00
P-470-100 100 g $ 282.00

Description

PMSF is a serine protease inhibitor that irreversibly inhibits serine proteases by sulfonylation of the serine residue in the active site of the protease. It is widely used in protocols for the isolation of proteins.

PMSF is inactivated in aqueous solutions. The rate of inactivation increases with increasing pH and is faster at 25°C than at 4°C. The half-life of a 20mM aqueous solution of PMSF is ~35 minutes at pH 8.0. This short half-life means that aqueous solutions of PMSF can be safely discarded after they have been rendered alkaline (pH >8.6) and stored for several hours at room temperature.

P-165-1 1 g $ 281.00
P-165-5 5 g $ 1,059.00

Description

Phosphinothricin is a broad-spectrum herbicide that acts as a competitive inhibitor of glutamine synthetase.

Glutamine synthetase plays an important role in plant nitrogen metabolism. Its actions lead to the formation of glutamine; however, when inhibited by phosphinothricin, a rapid accumulation of ammonia along with reduction in glutamine occurs within plants.

This herbicide makes an ideal agent for the selection of transformed plants. Plant resistance to phosphinothricin is conferred through the bar gene, and due to the fast degradation of phosphinothricin in soil and in water, it presents a low risk for environmental contamination.

Description

Phosphoenolpyruvic acid, trisodium salt heptahydrate is used as a reagent for the determination of glycerol. It is also a substrate for phosphoenolpyruvate carboxylase, which is an enzyme that catalyzes the addition of bicarbonate to phosphoenolpyruvate (PEP).

In bacteria, PEP acts as a source of energy for the phosphotransferase system (PTS). This mechanism involves the enzymatic extraction of a phosphate group from phosphoenolpyruvate. The phosphate group is then carried between several proteins until it reaches the sugar transporter known as EIIC.

Furthermore, PEP is used in research involving traditional cell-free protein reactions. These reactions require enough stable energy for protein synthesis. Since PEP holds the highest-energy phosphate bond among living organisms, PEP is commonly used for these reactions to produce ATP necessary for translation.
